I'm tempted to cheat with a hybrid: mascara-blush-concealer. That is to say, there are quite a few products I'd hate to live without.
Go without my thick, fluttering lashes (thank you, parental gene pool and DiorShow Blackout)? Without a rosy glow on my cheeks (the iconic Nars in Orgasm; the "cheeky"… get it?... name alone keeps me blushing)? And how will I survive those pesky under-eye circles without Benefit's It Stick? While I continue to rely on these prettifiers and camouflagers, I absolutely cannot live without my moisturizer. Sexy? Not in the least. Necessary? Indeed.
In Boston, we contend with whipping winter winds and drying office air. Before we know it, the sun's back and threatening to scorch our melting make-upped faces. Enter Garnier Nutritioniste's Skin Renew with SPF 15. My friend discovered the line while working on a PR campaign and had me at free samples. I've been using (and paying for) their products since those free samples ran out.
All the concealer and blush in the world won't make a difference if my face is parched, wrinkled or worse (year-round sunscreen: a must). And so, moisturizer it is!
